This may be a result of the recent upgrade, but all of a sudden enscape is replacing materials randomly..
This happened particularly on a 3d terrain generated by sketchup, then saved into archicad. The SAME terrain object had been displaying just fine a couple of weeks ago..
Note on the ENSCAPE image, the terrain (which is typically a patchwork quilt from sketchup) as replaced some terrain (aerial) squares with random other textures... some white brick, some tree bark, some roof tiles, etc.
You can also see that the same squares in archiCAD show as they should...
When a terrain is imported in archicad, the OBJECT contains all the materials in the script and saves a folder full of images as textures. Again, working fine in ArchiCAD and has all worked fine in the past in Enscape.
I'll try and revert enscape back a release and see if it's fixed..
